We investigate how differences in the stellar feedback produce disks with different morphologies in Milky Way-like progenitors over 1 ≤ z ≤ 5, using eight state-of-the-art cosmological hydrodynamics simulation codes in the AGORA project. In three of the participating codes, a distinct, rotation-dominated inner core emerges with a formation timescale of ≲300 Myr, largely driven by a major merger ev

Populärvetenskaplig sammanfattning:Elfordon uppfattas ofta som en modern uppfinning, men elektriskt drivna fordon har funnits sedan slutet av artonhundratalet. De första helelektriska personbilarna, bussarna och lastbilarna utvecklades redan innan förbränningsmotorn slog igenom.För att förstå varför elektriska störningar spelar en så viktig roll i dagens elfordon kan man börja med en enkel bild. TThe rapid electrification of heavy-duty vehicles has introduced traction voltage systems (TVS) with electrical scale and complexity not previously seen in on-road applications. Multiple power electronic subsystems interact through long cables and frequency-dependent impedances, making conducted electromagnetic interference (EMI) a system-level phenomenon. Differential-mode (DM) and common-mode (CM

In 1807, Britain outlawed the slave trade across its empire. Yet in the Cape Colony, households continued accumulating slaves for decades afterwards. New evidence from digitised tax censuses suggests the answer lies not in labour demand, but in the financial value of enslaved people as capital assets.

This article explores meaningful work across two frontline occupations, bank advisors and school­teachers. We build on narrative research focusing on the role of stories and storytelling in the sensemaking and identity construction processes related to work to explore the importance of oth­ers in the perception and construction of everyday work as meaningful. To study this, we examine the narrativ

Human peripheral blood mononuclear cells (PBMCs) can be easily sampled from healthy individuals and patients. Density gradient isolation from human blood or leukocyte concentrates yields a mononuclear cell population of mainly lymphocytes, monocytes, and natural killer (NK) cells. PBMCs are vital circulating cells of the immune system and rely on oxidative phosphorylation (OXPHOS) for their energy

Den här antologin visar vad som händer när skolans och universitetets världarmöts i genuin samverkan. Inom ramen för ULF‑satsningen vid Lunds universi‑tet har lärare, forskare, skolledare och lärarstudenter samt elever tillsammansutvecklat projekt som utgår från verkliga behov i undervisningen – och somsamtidigt bidrar till ny forskning.Genom konkreta exempel från grundskola, gymnasium och kulturs

A relationship between seismic wave velocities and the stress state of a material have been largely investigated in small scale lab experiments but never on a large field scale. For investigation of this relationship on a larger scale a 3-D seismic array have been built into a full-size railroad embankment model. Using the three component geophones with vertical and horizontal sledgehammer strikes

Drawing and sounding both rely on bodily movement as a basis for artistic expression. Movement provides the underlying spark that brings both visual and sonic practices to life. As part of a long-term research project titled ‘Sonic Kinesthetic Forest’, this paper reflects on a collaborative exchange between three researchers who use moving, drawing and sounding practices to deepen human relationsh

This workshop investigates sensory dimensions of trees as a way to build upon tree literacy efforts by researchers affiliated with the Concordia Tree Project on the Loyola Campus. As a laboratory of micro-forests for students and the Montreal community to learn about the wealth of trees on the campus, this forestry project aligns well with the cross-disciplinary project Sonic Kinesthetic Forest (S

The escalating energy consumption of existing artificial intelligence hardware has become a serious global issue that demands immediate action. Neuromorphic computing offers promises to drastically reduce this footprint. Here, we introduce multicomponent p-type Hf(Sr,Ti)O2 thin films for energy-efficient, resistive switching–based neuromorphic devices. We demonstrate interfacial memristors with ul

Short-term wave prediction is a key enabling technology for advanced control of wave energy converters (WECs), where accurate knowledge of the incident wave field over one to a few wave periods can improve power capture, reduce structural loads, and support operational decision-making. Many existing prediction methods rely on measurements at the prediction point or dedicated up-wave sensors, which

This thesis investigates the detection of acute heart failure (AHF) in an exvivo heart perfusion system using hemodynamic signals. Early detection of AHF is important for improving monitoring and intervention. Experimental data was pre-processed and transformed into a beat-to-beat representation, from which physiological features were extracted. Events were labeled based on manual reductions in pu

This thesis investigates the remanufacturing potential of the electric front cross differential (eFXD) within the context of the circular economy (CE) and the R‑framework. Environmental assessment, mechanical validation and structured component classification are combined to identify opportunities and limitations for remanufacturing. The results show that a limited number of components, the tube h

Emerging evidence suggests that bidirectional lung–kidney crosstalk may influence outcomes, but this has not been systematically evaluated in unselected emergency department populations. We therefore examined the association between peripheral oxygen saturation (SpO₂), estimated glomerular filtration rate (eGFR), and 30‑day mortality, and tested whether the prognostic association of oxygenation wi

We determine the composition dependence of the below-bandgap anisotropic refractive indices and dielectric functions of β-(AlxGa1−x )2O3 for x up to 25% Al. We use Mueller matrix generalized spectroscopic ellipsometry and investigate a set of high quality single crystalline bulk (x = 0 %, 5 %, 10 %, 15 %, 20 %, 25 %) and thin film (4.6%, 9.7%, 12%, 15%, 16.3%, 21%) samples grown by the Czochralski

Sonic Kinesthetic Forest is an interdisciplinary research project that explores novel methodologies for studying trees and forests through embodied sound, movement and drawing practices. Our video article reflects on this interdisciplinary research through the lens of a performance piece in which embodied sound, movement and drawing practices were intricately interwoven with a forest landscape.
